Maintenance and Calibration

Anadarko-(4)300w

Fluenta’s ultrasonic flare gas meters are accurate, reliable, and designed to withstand the harshest environments, both on land and offshore.

Flare gas measurement is one of the most demanding processes in the oil and gas industry.

Parameters such as gas composition, temperature, pressure and flow rates are constantly changing in flare lines. Fouling deposits including wax, tar, carbon, liquids and sand can also be present on the transducers in some applications.

All these factors can lead a flow meter to misreport flow, with clear direct financial consequences, as well as the potential for enforcement action from regulatory bodies.

As components in the system age, the continuous ultrasonic wave offset can shift, causing an increase in system uncertainty. Calibration corrects this offset and ensures your meter measures as well as it did when it left the factory.

A Fluenta Certified Technician

Shell-Albian-Sands300w

General inspection of meters is vital.
Whilst our meters are designed and built to be rugged, the tough environment can take its toll. Regular checks on electronics, seals, gaskets and explosion proof housings will ensure that you are never suddenly without monitoring.

Products change over time, and our engineers work hard to make sure they know all our equipment, both older models in the field and brand-new equipment leaving the factory.

Be certain that the technician you employ is certified. A technician without latest training could be a major risk to your equipment, or worse, to your plant. Accredited service partners will produce their credentials on request. If in any doubt, please contact your local Fluenta representative.

Support & Servicing

Servicing by a Fluenta certified technician is a comprehensive process and typically involves the following steps:

  • Cleaning of ultrasonic sensor probes
  • Zero-point calibration of the probes
  • Calculations and totalization check
  • Ultrasonic signals and configuration list download
  • Analog output calibration
  • Analog input for pressure and temperature calibration
  • Updating firmware
  • Calibration certificate
  • Service and status report

Input and Output Calibration

During service, inputs and outputs are checked with a certified loop calibrator and a calculated correction coefficient is set. This ensures proper system calculations and data acquisition.

Calculation Check

A calculation check ensures that all the flow meter calculations and settings are appropriate and internal clock cycles are correct.

Spare Parts

As the FGM 160 has no moving or wearing parts, few routine spares are required. These include:

  • Flanges
  • Ball valves
  • Pressure & temperature transmitters
  • FGM 160 Meter – board stack, cable glands, O-rings & fuses
  • Transducers & transducer cables
  • Packing box
